Yeah, it's less bias and more just chosen at random what points he'll give out which is based on how you perform (e.g. points for the one that jumped the most means the pokemon who...well, jumped the mosted in that event gets the points!).
Don't see much discussion coming from this minor misconception thrad, so going to close. (Already have a pokethlon discussion thread as well if you search for it). Any other questions, use the Help thread please.
